Alex Pietrangelo says the St. Louis Blues have only themselves to blame after their collapse in Game 1 of the Stanley Cup Final.

"It was more us," Blues captain Pietrangelo said, according to Tom Gulitti of NHL.com. "I think we got away from our game. We got spread out, allowed them to play the way they wanted to through the neutral zone."

The Blues held a two-goal lead early in the second period before Boston Bruins defenseman Connor Clifton opened up the scoring for the home side.

It was all Bruins from then on. They outshot the Blues 30-12 in the second and third frames, scoring four unanswered goals en route to a 4-2 victory over St. Louis.

"We just didn't get to our game at all," Blues forward Brayden Schenn said. "We turned over pucks, didn't support each other, started flipping the puck a lot. We weren't making a whole lot of plays, and it forced us to defend a lot."

The teams will be back at TD Garden on Wednesday night for Game 2.
